After pleasant weather earlier this week, expect conditions to get wet and windy today.

The National Weather Service has issued a flash flood watch starting from noon today (Friday) until 5 a.m. tomorrow (Saturday) for Fairfax County.

Isolated thunderstorms are expected to begin in the late morning today, with rain accumulations of up to a half-inch. The main storm front is expected after 4 p.m., with as much as two inches of rain possible across the county.

High winds of 11 to 15 miles per hour, with gusts as high as 30 miles per hour are also expected. Keep an eye out for hail too.

Here’s from Fairfax County Government:

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor weather forecasts and be prepared to take action should Flash Flood Warnings be issued.

If you encounter water on roadways, please remember — Turn Around, Don’t Drown! It is never safe to drive or walk into flood waters.
